The Tu-154 is powered by three rear-mounted
low-bypass turbofan engines arranged similarly to those of the Boeing 727, but
it is slightly larger than its American counterpart.
Both the 727 and the Tu-154 use an S-duct for the middle (number 2) engine.
The original model had Kuznetsov NK-8-2, while the Tu-154M has Soloviev D-30
engines.
All Tu-154 aircraft models have a higher thrust-to-weight ratio than that of the
727 – this gives them superior performance, although at the expense of poorer
fuel efficiency, which became an important factor in later decades as fuel costs
grew.

The Tu-154M and Tu-154M Lux are the most highly upgraded version, which first
flew in 1982 and entered mass production in 1984.
It uses more fuel-efficient Soloviev D-30KU-154 turbofans.
Together with significant aerodynamic refinement, this led to much lower fuel
consumption and therefore longer range, as well as lower operating costs. The
aircraft has new double-slotted (instead of triple-slotted) flaps, with an extra
36-degree position (in addition to existing 15, 28 and 45-degree positions on
older versions), which allows reduction of noise on approach.

All enginesounds are recorded in TSS HD audioquality, then compiled to meet the
FSX sound specification.

Besides the real high quality recordings of the engines, this soundpack also
includes fully adapted soundcones.
